Need some help troubleshooting
First post here...
I've got a 2004 motorhome on an E-450 chassis with the 6.8 V-10. The engine has 15,000 miles on it and has the 4 sp auto.
Recently, the tranny has started making noises during up and downshifts, usually under heavy load. See this vid for a good example:
6 8 V 10 engine - YouTube
Of note... The RV was designed for Canada, thus what looks like excessive speed for a 12,000 lb beast. Also, the check engine light was for the MAS. I cleaned that today and cleared the code.
Thanks in advance for the help!

I'll also add that when upshifting from 3-4, I'll sometimes get a small chirp/squeal out of the tranny. Again, the greater the load, the louder and longer the noise.
And I've also noticed a small buzzing noise whenever the gear selected is D. If I put it in P,R,N,2 or 1 the buzzing is not present.
If you've any ideas, I'd appreciate the help.

Believe it or not the noise sounds like ignition noise through the radio---is that even possible for your situation?
If so its most likely a bad ground connection somewhere in the radio circuit.
Not sure that's helpful but just an idea.

JWA- Had not thought of that. The radio is off during the video and for that matter most of the time we're driving. But I suppose that it could still come through if it was a grounded wire. I'll try pulling the fuse for the radio to see if that's what it is. Will be a few weeks before I can reply back. I'll be afloat for the next three weeks on a haze grey big deck.
